Bare with me now, as we are almost done!

Sand the inside of the fuselage with your 100 grit paper where the jamb will be glued on, as shown in the seventh picture below. Don't forget to wipe the fuse clean with some lacquer thinner.

Using a .050" drill bit, drill eight holes thru "Rivets" on fuselage, four above and four below the access door openings in the fuselage. By hand, use a 1/8" drill bit and counter sink these holes. Be careful and not drill all the way through the fuse. (That's why we're doing it by hand.)

Take the nozzel off your aeropoxy and squeeze about an inch and half on a mixing board, mix it throughly and apply to the edges of the door jamb and the long parts above and below the door, with the door closed. Keep the glue about 1/8" away from the door on the jamb as shown in the photo.

Start eight #0 x1/4" flat head screws in the holes in the fuselage.

Holding the door assembly (With glue applied) in place, with one hand, using the hinge at the top as a guide and centering it in the opening screw the #0 screws into the balsa door jamb frame, with the other hand.

Don't strip out the balsa as you want tighten them just enough to hold the assemblies in place. I started with the corners , then screw in the rest. Wipe away any excess glue that may ooze around the door.

Go on the inside of the fuse and apply a small fillit of aeropoxy around the frame and the reinforcing strips above and below the doors. Open both doors and let the glue set up.

Except for painting the inside of the doors and the jambs you are done with this useful detail.

More to follow in the coming days.
